ventrad; narrow; straight. FCu reduced distally; large; broadly ovoid; weakly convex. FA 

 small. Anterior margin entire; not reduced by FCu. AXCu absent. Suture line between 

 FCu and FA present. Suture line between FCu and AXCu present. Suture line between FA 

 and FJ absent. 



Neck elevated proximally; depressed distally. FCu section of neck absent. AXCu forms 

 entire neck. Proximal margin elevated as a broad ridge. Ridge extends to postero-median 

 of the proximal margin of tail; moderately long; enlarged dorsally relative to tail. Dorsal 

 surface of the ridge curves distad. Prong armed with a single short tooth; oriented proximo- 

 dorsad; narrow. Detached AXCu fragment saddle-shaped; strongly curved ventrad both 

 anteriorly and posteriorly; slender; moderately sclerotized. 



Tail deltoid; very broad; short: planate. Dorsal surface oriented mesad. Window absent. 

 FJ+AXJ narrow; occupies the distal half of the tail; moderately sclerotized. Suture line 

 between FJ and AXJ absent. Suture line between FA+AXJ and AXA present. AXA equally 

 sclerotized as FA+AXJ; the former occupies the postero-proximal half of the tail; straight. 

 Suture line between AXA and AXCu present. 



Hind Wing Base Description 



First Basal Plate (Fig.77) 



Humeral Plate moderately broad and long. Anterior margin convex; strongly sclerotized; 

 distant from BScA. Apex moderately narrow; curved ventrad. Dorsal margin concave. 

 Proximal margin weakly concave; curved proximo-ventrad. Ventral margin strongly 

 sinuate. Suture line between FPC+BPC and FC+BC present. 



Anterior Subcostal Basivenale broadly deltoid; strongly convex. Proximal and distal 

 sections separated by a prominent suture. Proximal section extends postero- ventrad as a 

 broad convexity; about as large as the distal section. Distal section continuous with ScA 

 bulge; separated by a weak concavity. Apex broadly rounded; oriented distad. - Subcosta 

 Anterior strongly convex. Bulge broad. Postero-proximal margin with a distinct ScA-BR 

 Brace. 



Radial Basivenale convex; closed; continuous with radial stem; angled proximad; 

 extremely broadly rectangular. Proximal arch strikingly broad; deltoid; continuous with 

 the anterior margin of BR; angled posteriad. Postero-distal section rounded. Anterior 

 margin strongly depressed below the posterior margin of ScA bulge; not visible dorsally; 

 weakly convex; angled proximad. Embayment normal sized. Distal arch very weak; 

 continuous with radial stem; oriented posteriad. br strongly sclerotized; occupies less than 

 half of the proximal arch; discontinuous with BR. br projection weakly distinct from BSc 

 as a long, dove-tail shaped extension. 



Second Basal Plate (Fig.78) 



MA-BMA Junction absent. - MP-BMP Junction: MP only very weakly continuous with 

 the anterior margin of BMP; arises from below the distal plate. - Crimp Patterns absent. 

 - BMP-CuA Brace absent.
